UNITE 'TATES JAMES L. RECORD, OF MINNEAPOLIS, MINNESOTA.

FIREPROOF GRAIN-ELEVATOR.

SPECIFICATION formingpart of Letters Patent No. 670,456, dated March 26, 1901.

To aZZ whom it may concern:

Beit known that I, JAMES L. RECORD, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Fireproof Grain-Elevators, of which the following is a specification.

My invention relates to elevators for the storage of grain. In such buildings Wooden bins are generally regarded as preferable to metal; but the difficulty of satisfactorily combining Wooden bins with a metal building structure has resulted in the almost universal use of either wood alone or metal alone in the erection of such buildings. To obtain the advantage of the use of wooden bins and to satisfactorily combine them with a metal framework and make the whole fireproof is the principal object of my invention.

My improved structure is preferably made to rest on pile, concrete, and stone foundations; and it consists of steel, terra-cott'a, concrete, masonry, &c., with Wooden bins. The metal beams, columns, 850., are protected by fireproof material,the bins consisting of planking laid up in the usual manner, exposed portions being protected by brick or tiling and the bottoms composed ofsteel beams, tiling, and concrete, and the cupola is a skeleton of steel with fireproof flooring and exterior walls of tiling secured to the steel frame.

My improvements are illustrated in the accompanying drawings, in which Figure 1 shows an end portion of a transverse vertical section of a grain-elevator containing the improvements. Fig. 2 is a similar longitudinal section. Fig. 3 shows in longitudinal section a portion of one of the bins, its concrete bottom, and the means for supporting the concrete and for supporting the bin-walls. Fig. 4 shows a similar sectional view of one of the'narrower bins adjacent to an elevator-leg. Fig. 5 is a similar transverse section showinga portion of the building-wall and the nearest bin. Fig. 6 is a view similar to Fig. 5, but showing also a portion of an elevator-leg. Fig. 7 shows in transverse section a portion of the cupola. Fig. 8 is aside view of the end column of the cupola at the mezzanine floor. Fig. 9 shows the floor construction of the working or ground floor, Fig. 10

is an enlarged View of the lower right-hand portion of Fig. 7, illustratingthe supports for the cupola and the floor construction shown in Figs. 7 and 9. Fig. 11 is a still further enlarged view showing the floor construction. Fig. 12 is a section of the top of the inside column shown on the line 0 Ct of Fig. 4. Fig. 13 is a sectional view of the wall and column construction on the line b b of Fig. 6. Fig. 14 is a sectional View of one of the interior columns, showing the manner of fireproofing;

and Figs. 15 and 16 show in sectional elevation and plan, respectively, details of the arrangement of the self-adjusting anchors for the exterior Walls. v

In the drawings, 1 designates the piling, 2 concrete around and over the top portions of the piles, and 3 a cement covering, constituting the floor and base on which the foundation-stone's 4 are. laid. The main or working floor 5 should be fireproof and preferably of the construction hereinafter described. The columns 6, which rest on the piers 4,are preferably composed of steel plates 7, united by angle-irons Sin the usual manner, and are protected by surrounding them with jackets 9, of steel or woven wire, and a filling 10, of cement or other fireproofing substance.

The main beams 11 for supporting the bins rest immediately upon the columns and extend across the building, and upon these are seated other beams 12, extending at right angles to them or lengthwise of the building. On the beams 11 and 12 is laid brickwork 13 to a common level slightly above the tops of the beams 12, and on the brick are placed the sills 14:, upon which the bin-cribbing 15 is laid. At two diagonally opposite corners of each bin are short bases 16, secured on the sills 14: for the posts 17, which extend to the tops of the bins for supporting the cupola. On the tops of the posts are beams 18, secured by angle-irons 19, and upon these beams the cupola-posts, which are formed of angle-plates 20 and latticed bars 21, are seated.

The beams 11 and 12 are secured together and to the columns 6 by bolts 22, having'nuts at the upper ends engaging plates 23 on the upper beams, and nuts at the lower ends eugaging plates 24 at the lower'edges of sleeves 25, that have flanges 26, by means of which they are riveted to the columns. The beams 11 are secured on the heads of the columns by bolts 27, with nuts above engaging plates 23 on the beams and other nuts below ongaging lateral angle-irons 29, that are riveted to the columns and abut vertical plates 30, that are also riveted to the columns. The sills 14, upon which the bin-cribbing is built up, are secured in place by bolts 31 to the beams beneath them.

The beams 32 for carrying the cones or centers of the bin-bottoms are supported by stirrups 33 from the beams 12, so that the former are below the latter beams. Arches 341, of hollow tile or other fireproof material, are sprung between the beams 32 and the beams 11 at the heads of the columns for carrying the concrete filling 35, which forms the interiors of the bin-bottoms. It is desirable that these arches be of hard-burned hollow tile and the abutment-tiles of specially-designed form to fit the girders in such a manner that no metal-work will be exposed to the action of fire from the outside. The concrete 35 is filled in and built upon the tile arches 3% to form fireproof hopper-bottoms for the bins, which taper in funnel shape, as shown, to the metal discharge-spouts 36.

It is unnecessary to fireproof the partitionwalls between bins, but all partitions between the bins and the chambers through which the elevator cases or legs extend are fireproofed. This is done by tile walls 37, built around the elevator-legs from the bottoms to the tops of the bins, preferably in two thicknesses of tile, the outside tile being salt-glazed and the inside porous terra-cotta secured together by metal clamps. The bottom of the elevatorchambers are fireproofed by a cement filling supported on tiles, as in the case of the binbottoms, and the passage-ways through the hopper-shaped bottoms are metal boxes 38.

Around the exterior of the framework are brick walls 39. The lower portions of the walls to the level of the tops of the beams 11 are built partly around the outside columns 6, as indicated in Fig. 5; but above that point to the first or distributing floor of the cupola the walls are thinner and a space intervenes between them and the bin-walls. To anchor these upper portions of the walls and at the same time arrange the anchor devices to properly adjust themselves to the unequal settling of the bins relative to the walls, the anchors are comprised of two members 40 and 41, adapted to slide upon each other, the one being secured to the wall and the other to the bin. As illustrated, the part 40 has horizontal arms embedded in the wall, with a loop projecting into the space between the wall and bin, and the member 41 has a vertical portion extending through the loop of the other member and horizontal arms secured to the bin. Thus any inequality of settling of the bin and wall will cause the anchor members to slide on each other without interfering with their efficiency as anchors for the wall.

The cupola to the top of the distributingfloor is inclosed by hollow tile walls -12, built up from the brick walls 39. Anchor-rods 1-3, of any suitable form, may be used for connectin g the tile walls to the cupola-framework. The upper and narrower portion of the cupola is also inclosed by tiling 44, built up from shelves 45, attached at suitable intervals to the outside posts 46 of the cupola-framework. These tiles may also be secured and anchored in any desired way. The outside columns of this framework are preferably incased in terra-cotta.

The roofs are preferably composed of T-iron rafters 47, between which are laid terra-cotta book-tiles 48, on which fireproof roofing-felt 49 is secured.

The eupola-floors are composed of porous terra-cotta tile 50, laid in place and bedded in cement 51 on a metal fabric 52 and supported by metal joists 53. The tops of the bins (at the distributing-i100r) should be covered with a similar or a book-tile flooring. The working or ground floor 5 may be similarly constructed.

By the employment of the means set forth an elevator-building combining the advantages of wooden bins and a fireproof structure is produced, and the bad effects of unequal settling of the bins and building are overcome, the bins being supported independently of the building-walls and their anchor connections being self-adjusting.
